The poison glands open through the claws of the first pair of legs, which are bent forward so as to act with the mouth parts. These creatures abound in all parts of the United States; those which are found in the North are comparatively small, and rarely, if ever, inflict serious injury to man ; but the larger species, which occur in the warmer regions, are said to be extremely venomous. The centipedes are predaceous, feeding on insects ; they usually live under stones, logs, and bark. There is one spe- cies, Cer7natia forceps (Cer-ma'ti-a), which has very long legs, and only fifteen pairs of them, which is often found running on the walls of houses, especially in the Southern States.
